The invention discloses a power-assisted steering control method of a walking aid, a power-assisted steering control device and a storage.The power-assisted steering control method comprises the steps that the first moving speed of a left wheel and the second moving speed of a right wheel are obtained, whether the left wheel and / or the right wheel are / is in a steering state or not is judged, and if yes, the power-assisted steering control device is started; if yes, a steering angle estimated value or a speed difference value between the first moving speed and the second moving speed of the right wheel is calculated according to the first moving speed and the second moving speed, a steering power-assisted compensation value is obtained according to the steering angle estimated value or the speed difference value, and power-assisted compensation is conducted on the left wheel and / or the right wheel. According to the walking aid, more labor can be saved when a user pushes the walking aid to steer, a user with small strength can use the walking aid more conveniently, the influence of steering on the advancing speed of the walking aid is reduced, normal advancing of the walking aid is guaranteed, sudden pause caused by increase of steering resistance is avoided, and safety can be improved.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a steering assist control method, a steering assist control device and a memory of a walker. Background technique [0002] Walking aids can be supported by equipment, so that the elderly, patients with inconvenient legs and feet, and even people who have lost the ability to walk can go out and walk like normal people. The user inevitably needs to perform operations such as steering during walking. [0003] At present, the steering of the walker is completely realized by the force exerted by the user, and the resistance when turning is greater than that of the straight line, and the users of the walker are generally special people with less strength, so when the steering resistance increases When it is large, it will cause inconvenience and affect the user's progress. Contents of the invention [0004] The invention provides a steering assist control method of a walker...
